Time dependence of the e-flux measured by PAMELA during the 2006 July-2009 December solar minimum
(IOP Publishing, 2015)
Precision measurements of the electron component of cosmic radiation provide important information about the
origin and propagation of cosmic rays in the Galaxy not accessible from the study of cosmic-ray nuclear
components ...
Cosmic rays in astrospheres
(EDP Sciences, 2015)
Context: Cosmic rays passing through large astrospheres can be efficiently cooled inside these “cavities” in the interstellar medium. Moreover, the energy spectra of these energetic particles are already modulated in front ...
A numerical simulation of cosmic-ray modulation near the heliopause
(IOP Publishing, 2015)
Based on a hybrid galactic cosmic-ray transport model, which incorporated MHD global heliospheric data into
Parker’s cosmic-ray transport equation, we studied the behavior of the transport of galactic cosmic rays and ...
New modeling of galactic proton modulation during the minimum of solar cycle 23/24
(IOP Publishing, 2015)
During the recent prolonged solar minimum of cycle 23/24, the PAMELA detector measured 27-day averaged
Galactic proton energy spectra over the energy range that is important for solar modulation. By comparing these
spectra ...
H.E.S.S. reveals a lack of TeV emission from the supernova remnant Puppis A
(EDP Sciences, 2015)
Context: Puppis A is an interesting ~4 kyr-old supernova remnant (SNR) that shows strong evidence of interaction between the forward shock and a molecular cloud. It has been studied in detail from radio frequencies to ...
Modulation of galactic electrons in the heliosphere during the unusual solar minimum of 2006-2009: a modeling approach
(IOP Publishing, 2015)
The last solar minimum activity period, and the consequent minimum modulation conditions for cosmic rays, was
unusual. The highest levels of Galactic protons were recorded at Earth in late 2009 in contrast to expectations. ...
Probing the gamma-ray emission from HESS J1834-087 using H.E.S.S. and Fermi LAT observations
(EDP Sciences, 2015)
Aims: Previous observations with the High Energy Stereoscopic System (H.E.S.S.) have revealed an extended very-high-energy (VHE; E> 100 GeV) γ-ray source, HESS J1834−087, coincident with the supernova remnant (SNR) W41. ...
